EYELETING-MACHINE.

Patented Oct. 1, 1907.

To all whom it may concern:

13o it known that we, XlflliflLA-H T. lnuzsu, Jens G. Oottn'nr, Mn/rox U. Kln'ten, and LOU-S (jnunnn,

county of lilontgolncry and Slate ol' ()hio, have invented certain newand u eful improvements in Eyeleting- I Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reierence hting had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification i This invention relates to new and useful improvements in lllachines for attaching gron'iets to fabrics or other material such as canvas. leather, etc.

The object of the invention is to provide a machine which, in one oporatirm, will perforate the fabric or material and unitc the male and female gromets to complete the eyelet.

The invention consists broadly in the means for for automatically feeding the female grometsy'into Preceding a'deta-il description of the invention, reference is made to the accompanying drawings, of

In a detail description of the invention, similar reierencecharacters indicate corresponding parts.

The framework of the machine may he of any suitable design to'provide the necessary space. As shown in the drawings it consists of two upright parts l which are joined by integral'cross-pieces 2 and'in the forward portion of which two heads 2 are located ior thegromctclenching devices to be hereinafter described. The operations of the machine depend in the main upon three master cams which'are cut in disks 4-5 and 7 arranged upon a common shafttl having suitable hearings in the frame; these internal cams are desig,- nated '36 and 8 and from them the necessary movements are imparted to the gromet hoppers 12 and;13 and their respective chutes 10 and 11 to be hereinafter described. Power is transmitted to the cain shaft 9. from the main power shaft 25 which carries a beltpulley 27 and also a pinion 26, the latter pinion meshes with a larger spur. wheel 28 of suitable diameter upon' Fig. 18, is a Fig. 19, is a detail view of the cam shaft 25".; from the latter 'shaftpower is transmitted to the cain shaft 9 from a pinion 29 on said shaft 25 which meshes with a large spur wheel 29 on the cam shaft. On-a. face of. the spur wheel 29 there is a-clutch member 35 which is adapted to engage with a clutch member 36 which is slidably mounted on the cam shaft 9 and is operated through a shifting lever 3'2 pivoted at 38 and having adownwardly extended connection 39 which is operated. by. means of a foot'treadle (not shown) to throw said clutch into engagement; at a complete revolution of the cam shaft the clutch membore 35 and 36 are thrown out of engagementas in Figs.

' which act upon' connecting rods' 14 and 15 which are pivotally connected to said chutes 10 and 11 and are fulcrume'd upon. a boss .16 extending irornthe frame. The lower ends of these connecting rods or bars 14 'and 15 carry rollers 21 and 22 which lie within the internal cams 3.9.11 6. The forward ends of said chutes are supported b means of pivotal Links 20 and 21 whicharg pivot-ed to a boss 18 projecting from the 11119 for the male gromets is shown in detail on Sheet 4 and- 1s of suitable capacity; the chute 10 extending from this hopper contains a male g'romet 4'4 just in the act of entering said chute and into which said gtomets are periuittcdto pass one at a time through the opening 47 which is shaped to permit of but the single male gromet entering the chute at a time. In the rear of the chute there is a lever48 fulcrumed at 49 and having two pins 45 and 46, the former of which is adapted to obstruct the entrance 47 from the hopper to the chute, and the latter pin, to-wit fld, catches each gromet after'it has passed from the hopper to the chuteand releases it to permit of its passage down the chute to the position'shown in Fig.1], where it is arrested by a detent 50', from this position the male gromet 44 is passed out to the end of the chute and the punch 51,

to be again referred to.

v The lever 48 is normally pressed out to the position in Fig. i5, by a spring 52, and said lever is operated against the tension of said spring and during the opera tions or movements of the chute by coming in contact with a pin 53 which lies transversely of said lever and supported upon an upright 54' fixed to the frame-werk of the' machine. The male grornets within the hopper 13 are agitated by a brush 55 which is fixed to a shaft 56 rotated through means of a pulley 57, which is connected to a pulley 32 on the main driving shaft 25, by a belt or chain 30 which passes over upper pulleys 33 supported at the rear of the hopper 13 and thence around the pulley 57. The hopper lZ'for'the female gromets is at the upper end of-the chute l1 and contains a rotatingplate '23" which has a suitable number of openings 17 therein which are adapted to contain but a single female grometat a time. The space beneath these openings 17 is such that the female groinets cannot find lodgcruent therein unless the said gromcts are in a position with the concaved sides thereof down;

this limited spaceis shown in Fig. 14 and it is important that said female gromets be soot-impelled to enter the chute 11 in order that they may be presented in a proper position for the clenching devices to act thereon in uniting the two gromets to the fabric;

The hopper may contain any desirable number of gromets which are picked up bythe openings l7 when said gromets are in proper positions as hereinbcfore described 'and the plate 23" is rotated by being fixed to ashaft/l3 having a pulley 58 thereon; this pulley is connecled to a pulley 32" on the intermediate driving shaft lfifithrough'suitable belts or chains 31 which pass over upper pulleys 33 atthe rear ofthe chute l2 and is thence carried around the pulley 58. The female grornets so picked up'in the openings l7 of the plate h 23 are released by a slide 59 which projects into the hopper 12 below the revolving plate 23", and when this slide 59 is withdrawn from the hopper, the gromet lying in the opening 17 above said'slide 59 is permitted to drop into the passageway 60 through which it fails head of the punch 51 is a spring 69 which by gravity into the chute ll. The slide 59 is tripped to thus release the gromots by means of a suitable lever 61 which has one end connected with the slide and the other end connected witlra trip connection 62 which extends down and connects with a pivotal arm 63 which is tripped by a projection 64 on acollar ($5 on the cam shaft 9. Each revolution of the cam shaft trips the slide 59 a sul'iicient length of time to permit one gromet to drop into the passage 60, owing to a proper ratio. ofthe gearing; the same complete revolution of the-cam shaft completes the operation of uniting the gromets to the fabric; and the mechanism of which willnowbe described. Movably mounted in .the lower head or socket 2 is a plunger 34 which isxconnected to abell crank lever 23 pivoted M23" and currying on its lowcr'arm a roll 24- which lies in the internal cam 8 of the disk 7--see.i-l igs. l: and 15. The lllle(' tion between the bell crank lever 23 and the plunger 34 is by means of anfapertured head (in and a pin 67.

Supported in the upper end of the plunger 34 a punch 51 before referred to, which passes through an' apertured-anvil 68 which screws into the upper end of said plunger 34. Within the plungcr and below the exerts now mal pressure upwardly on said punch. The upper surface of the anvil .68 supports the male gi-omct 44 I when delivered thereto by the chute '11 with the point of the punch 51 projecting through the oponingin said gromet. The surface of the anvil 68 below thegrornet is provided with. an annular recess into which the gromet is pressed when prcssure exerted thoroag'ainst in bringing the parts together seeligs, 4 and 15. The upper onstationary incinbcr ol the clenching devices consists of a clenching block T! which has a lower projecting portion 72 with u ri-ccss, tin-coin de- .signed to receive the point of the punch 5] when tho parts are brought together in the com pletcd opm-aiion of uniting the gromet's to the fabric as shown in Fig. '15. In elevating thc'punQch 51, the fabric 74 is pm? fe rated thereby to form thc opcniug around which the male and female gromcts are united, said fabric alter bein so unctured is resscd down u )lln then nor P A l r l.

surface of the male gromct lying upon the anvil (i8 and the extension 75 of the male gromct is clenched over against the upper side of the female grometand thus unites the two gromcts with the i'abric between When the punch 5i enters the iemale'gromct which is supported on the end of the chute 1,1 as shown in Fig. 3, the said chute moycs rearwardly out of thc way and the punch 5]. llwvcls upwardly to engage the projection of the clcni'hing block 71. When the parts thus ongagcftlic. punch {ii is pressed r'lnwnwardly against. the spring (SS! us sluurn in Fig. 15. The clenching block H is si-n-u'cd inlo tho cylindricalportion 74", the upper end of which ox n-m ls in the form of a screw 76 which is scrcwcd iln'ough a cap 76 which is'fastcncd on the Lop of iluupper sm'kvl. 2"; it 'will thus be soon that the position of [he e-ll'nl'lllng block 71 may'bendjustcd by turning the screw To in tindesired extent to raise or-loivcr said block. 7

In the operation of clcnchingthc nmliand l'l-mulc gromets mgcth'ci, it is ncccssary that :lni'muulu gromct bc liulil lcvcl upon the upper surfacioi the r fabric; this is accomplished by means of a plurality of pass through openings in the .clcnching block 71 to make contact with the upper surface of the female gromet 43see Fig. 15. The plate 78 has a coil spring 79 above it which normally holds the pins 77 in contact with the gromet and as said gromet is moved upwardly, the pins 77 likewise n'loveupwardly against the tension of said spring 79.

Briefly described, the operation is as follows: A male gromet is removed from the end of the'chutc 1.0 while said end is in proximity to the punch 51, said punchbeing elevated to enter the gromct; the chute 10 is timed to move rearwardly and to thus have the gromet upon the punch as shown in Figs 1. and 4, or

the said. male gromet may be removed iromthe cluite by hand and placed in such position upon the punch. Theiabric is then placed liylthe hands above the punch and the continued upward movement of said punch perioratessaid fabric to forin the hole therein; in the meantime, the female g romet is supported in position on the chute 11 above the punch 51, and the said punch penetrates said gromet at which time thechute 1l recedes out of the way; the leveling pins 77 next engage the gromet43 and maintain said gromet in position around the punch 51 until the parts are pressed together to the limit as shown in Fig. 15. In this view, it will be seen that the'shank of the male gromet extends -through the opening in the female gromet and is clenched over against the surrounding edge of said female gromet. All this, to-witthe making of the opening in the fabricv and the uniting oi the two gromets being done in one operation and during one revolution of the crank shaft 9.
